Hi Blacktubi, which one is better between this one and TP-Link Archer GE800? BTW, great article!
They are different thing I would say. Archer GE800 comes with tri-band 6GHz but this ASUS RT-BE88U is only dual-band. The GE800 comes with the 6GHz band but the 5GHz and 2.4GHz performance of RT-BE88U is much faster than the 2.4GHz and 5GHz of Archer GE800.
Wah never expected. So overall RT-BE88U better?
It depends on your priority. RT-BE88U does not come with 6GHz at all. Meanwhile Archer GE800 comes with the less congested 6GHz band and it can deliver over 2Gbps on WiFi. But it’s only able to do that when you’re physically less than 5 meters to the router.
Hi Blacktubi. Off-topic, but would you be able to review the GL.iNET Flint 2? It seems to be punching above its weight in terms of features and performance.
Let me try to send them an email and see if they are willing to send us an unit for review.
Ah the popular question would be, does the SFP+ port work with Unifi 2Gbpe connections? direct fiber ISP cable to the router. How much speed was attained? Thanks BlackTubi.
The thing is using non-TM approved fiber modem or SFP+ module is actually prohibited by TM. And, it’s not a straight-forward plug n play process. Hence, I try not to advocate about it.
Nice review. Where’s your cafe located? =P
Nice find! It’s actually not a real cafe, just to show how the feature on the latest ASUS routers work.
